Objective To study the CT findings of the herniated lumbar disc on sagittal and coronary plain.

目的 研究腰椎间盘突出在矢状位、冠状位上的CT表现。

Predisposing factors leading to SSS thrombosis may be grouped into one of three categories: hypercoagulable state, venous flow disturbance, and in association with infection or inflammation.

导致上矢状窦血栓的致病因素可以分为三类：高凝状态、静脉血流紊乱、炎症或感染相关状况。

In sagittal plane,the PPSI of each level moved from inferoposterior to superoanterior with an arc trajectory.The PPSI displacements and angular variation increased from L1 to L4,however,these two decreased in L5 simultaneously.The rotation radius had no relationship with lumbar segment.Flexion-extension ROM from L1/2 to L5/S1 increased gradually.

各腰椎屈伸运动时PPSI矢状位上呈由后下至前上的弧线轨迹，L1~L4其位移量和倾斜角度逐渐增大，L5两值同时减小；其旋转半径与腰椎序列无明确关系。L1/2至L5/S1屈伸活动度逐渐增加。

Coronal and sagittal CT reconstructions demonstrate the intravertebral vacuum.

冠状位及矢状位的CT重建示椎体内真空。

Results Sagittal MRI revealed horizontal intravertebral area, hypointense on T1-weighted images and hyperintense with surrounding band of hypointensity on T2-weighted images.

结果 矢状位MRI显示水平方向的带状区， T1加权像为低信号， T2加权像为高信号，周围有低信号区包绕。

Loaded the simulated acetabular cup at an inclination of 35°, 40°, 45°, 50°, 55° to 6 cadaver pelves. Made the pelves tilt around the frontal axis and sagittal axis with 5° each time in a scope of ± 30°. Take standard radiograph of the pelvis accordingly.

按35°，40°，45°，50°，55°外展角分别放置于6具防腐骨盆标本髋臼窝内，使骨盆标本沿冠状轴、矢状轴在±30°的范围内按5°/次分别旋转，保持X射线投照中心点始终与标准骨盆正位片投照中心点一致。

METHODS: Puncture with the needle retaining in the cavity of knee of normal adult corpse without effusion or pneumatosis was performed, and 1, 5, 10, 15, 20, 30, 40 mL contrast-medium was injected into the cavity. Coronal section, vertical plane and transect were scanned with T2WI, 4 mm thickness and 1 mm interval by MRI.

对10件无积液、积气、结构正常的成人尸体膝关节腔内穿刺留针，通过穿刺针向关节腔内依次注入1，5，10，15，20，30，40 mL对比剂，分别于每次注射后行冠状面、矢状面、横断面T2WI，厚度4 mm，间距1 mm，MRI扫描。

Methods Through the 40 cases of healthy adults living tibia for the CT scanning and three-dimensional image reconstruction,the anatomy characteristics of posteromedial distal tibia were measured.

通过对40例健康成人活体胫骨进行螺旋CT扫描并重建三维图像，测量胫骨远端后内侧解剖学指标，包括在矢状面上的胫骨远端后翻角度、扭转高度，远端横断面上置钉安全区高度。

The sagittal view also assists in the diagnosis of the holoprosencephaly complex when a proboscis is demonstrated, or in the diagnosis of bilateral cleft lip and cleft palate with demonstration of a small premaxillary protrusion.

在矢状面探查到喙鼻也有助于诊断全前脑；如果观察到小的前颌突起则有助于诊断双侧唇裂和腭裂。

The two most commonly used surgical techniques to setback a prognathic mandible include the bilateral sagittal split osteotomy and the vertical ramus osteotomy.

二种最普遍使用正颚手术方法来改善下颚骨前突症的方法是双侧矢向面骨切开术及垂直下颚枝骨切开术。
